New app could detect early signs of drug overdose

By  | 

WASHINGTON (AP) Wondering if someone is suffering from an overdose? There's an app for that.

It's still in the experimental stage, but the "Second Chance" app is showing promise. Researchers say it appears to be able to detect the early signs of an OD in the critical minutes after a person takes heroin or other illegal drugs.

The app beams sound waves to measure breathing and can summon help if it detects a person has stopped breathing.

One issue to tackle: whether drug users would take out their phone and fire up an app before shooting up.

Despite that concern, researchers from the University of Washington say the app could be an important tool to help those who haven't yet been able to obtain addiction treatment.
